`Application filed December 29, 1921. Serial No. 525,806.`

To all-whom it may concern.'

Be it known that I, JOHN B. NAINTEAU, a citizen of the United States,residing at WVoonsoclret, in the county of Providence,

State of Rhode Island, have invented certain` new and usefulImprovements in Spindles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in spindles andparticularly to spindles used in spinning machines.

One object of the invention is toprovide a construction and arrangementof parts which will insure the retention of. a sufficient quantity oflubricant to require attention only at widely separated intervals, andin which the lubricant will be prevented from being thrown outwardlyfrom the device, by centrifugal force.

In devices of this character the lubricant travels upwardly on the bladeof the spindle and then is thrown outwardly, against the inner face ofthe whirl, from whence it runs down and is thrown outwardly from thelower edge of the whirl. It is the particular object of this inventionto so construct the A blade and socket in which the lower end of theblade is disposed as to cause the lubricant to be thrown against theinner face of the socket, from whence it returns to the felt lubricantwasher.

Also, the wall of the socket has heretofore been formed with a downwardtaper at its lower end, and cylindrical near its upper end, with theresult that the space around the lower tapered end of the blade isnarrower at its upper end than at its lower end, thus causing the bulkof the oil to remain in the lower portion of the socket, and preventproper distribution of the oil tot the other portion of the blade. Inthe present invention the oil space in the socket is enlargedVthroughout its length so that a maximum quantity of oil will be retainedtherein and the blade more properlyy and equally lubricated.

Other objects andadvantages will be apparent from the followingdescription when taken in drawing; i

connection with the accompanying Referring particularly to theaccompanying drawing, 10 represents the base of the spindle, which hasthel upwardly extending reduced tubular extension 11. The boreof l thisextension extends downwardly into the base, as shown at 12, where it istapered, and y has. its .upper `portion cylindrical and cutcomparatively .deep into the -wall'of the eX- tension, as shown at 13..VScrewed onto the upper end of the extension 11 is a cap 141:, which hasits upper endformed with an inwardly directed flange 15, the inner faceof said ange being undercut or beveled, as shown at 16, to engage withthe upper end of the extension. The sleeve 17, of the whirl, fits downover the extension 11, 'and has the blade 18 disposed longitudinally andcentrally therethrough.

The lower end portion of the blade 18 is tapered and fits into thetapered portion 12,

of the bore of the base. The portion of the blade, from the upperend ofthe tapered portion, to the upper end of the sleeve 17, of the whirl, iscylindrical, as clearly seen in the drawing. It will be noted that theoil recess 13 is of a length toy extend throughout the greater part ofthe tapered portion of the blade, with the result that a larger quantityof oil will be retained therein, than in the recesses ordinarilyprovided. The upper end of the base 10 is formed with the usual cup 19in which is disposed the felt washer 20, for retaining the oil, achannel 21 being formed from the bottom wall of the cup downwardly andinwardly into the recess 13, a metal washer 22 being disposed on theupper end of the cup, over the felt washer.

The upper end of the extension 11 is bored out to form the shoulder orledge 23, and formed downwardly and inwardly, in the wall of theextension, from` the upper face of the shoulder to a. point above thecup 19, is a channel 24.

`Secured to and encircling the portion of the blade 18, immediatelybelow the upper end of the sleeve lof the whirl, is a band or collar 25,which, when the blade and whirl are properly disposed with relation tothe extension of the base, lies below the beveled mouth of the cap 14,so that the oil which travels upwardly on the outer face of the bladewill be thrown outwardly against the upper end of the interior of theextension 11, from whence it will run down through the channel 24, intothe recess 13, and spread on the adjacent portion of the blade.

rIhe lower end of the sleeve 17, of the whirl, is formed with aperipheral flange 17', in the upper face of which is formed a circu largroove 26, for the reception of' the bill 27 of the hook 28, which hookis pivotally carried by the base. Thus, as the whirl rotates, and has aslight tendency to rise, the bill of the hook will be retained in thegroove,'so that all danger or" the hook being released is obviated.

By this construction a larger quantity of oil will be reta-ined in closeproximity to the blade of the spindle than in spindles heretofore, andalso the oil will be prevented from passing upwardly along the blade byreason of the collar 25. This arrangement also prevents the oil frombeing thrown outwardly against the inner face of the whirl, from whenceit would reach the lower end of the whirl, and be thrown outwardly fromthe flange 17. Furthermore, the loss of time, in oiling spindles, isreduced to a minimum, and the quality of the product improved.

What is claimed is:

1. A spindle for spinning machines including a base, a blade mountedwithin the base and having a whirl, a collar upon the blade within thewhirl, and a flanged cap mounted upon one end of the base and encirclingthe collar.

2. A spindle for spinning machines including a base having open andclosed ends, ablade mounted within the base and having a whirl, a collarupon the blade within the whirl, and a flanged cap mounted upon the openend of the base with its flange positioned exterorly of the collar.

3. In a spindle, the comb-ination with the base, the blade having acollar, and the whirl, of a flanged cap on the upper end of the basesurrounding the collar to prevent lubricant being thrown against thewhirl.

4. In a spindle, the combination with the base, the whirl and blade, thelatter having a collar within the whirl, of' a flanged cap on the upperend of the base with its flange surrounding the collar above the lowerface of said collar.

In testimony whereof I affix my signature.

JOHN B. NAINTEAU.
